The valve head l2 is adapted te be depressed against" the action of the spring 33 and permitted to t be raised by the spring to close or partially close and open the passageway 3l by means of' devices and for a purpose which will be hereinafter explained. Surrounding the pipe 21 and port 31 therein in spared rela4 tion thereto is a baille sleeve 3l whieh ein tends downwardly a distance below lhe port 31 to provide an annular spaee 35. the batlie sleeve 34 heilig open at its bottom and closed at its top. as shown. The sleeve let is provided `with a series of perforations 3G preterably located above the port 31, The baille sleeve 34 communicates with the earbureting chamber through the open bottom ot the Sleeve and the perforations 36, so that when air is drawn through the earbureting ehamber, oil will he drawn from the port 3l and caused to strike the baille sleeve 34 and afterward to the arbureting chamber through the perforations 36 and the open bottom of the sleeve, thus atomizing the oil or breaking it up into linely divided pa rtieles as it enters the earbureting chamber.

The valve for eontrolling the llow ol' air through the carbureter eomprises a cylindrieal body S7 mounted within the easing 9 and lltted to turn on a horizontal axis therein.

the said cylindrical body 37 provided Willi a passage way 38 exteiiding,r therethrough transversely to its turning axis. The passage way 3S forms a part ol the ear-- bureting Chamber inelosed b v the easing il and the passage way 53S forms a part ot" the earbureting eliamber inelosed by the easing 9 and the passage way 25S is substantially the same in diameter as the vertieally extending inlet opening l() and outlet. opening ll ot' the valvi` i'hamber so that the valve 2li' may be turned to the l'ull open position shown in Fig. l to bring the passage way into registry with the openings lt) and 'll to permit a large volume ol air to he drawn therethrough: and so that the valve 37 may be turned to the position in Fig'. 2 or to any position intermediate the position shown in .l `igs. l and 2 to redueethe volunieotI air pass ing through the earbureting 'hamber. and thereby regulate the volume oti air in aeeordanee with the speed ot' the engine. 'l`lie valve body lli" is provided at one end with 'i solid sten ill and at its other end with 'i tubular stem ll) extending outwardly at their respective ends throngl'i the end walls. 4l and 42. respeetively ol' the easing il. rl`heI outer end of the tubular .stem 'lll has an arm 4-5 adjustably seeured thereto and by means otl whieh the valve I5? may be turned.

li'hen the valve Iii' is moved to the position shown in l"i; l the valve head L is simultaneously mined under the tension olf the .spring l-l toopen thepassage way Sil and when the valve 25T is moved to the position Shown in Fig. i2 the valve head :l2 is moved to close the passage way 3l and `for this purpose there is provided the following meehanism: Ixtending axially through the tubular valve stem nl() is a shaft il the inner end ot which is provided with a evlindrieal projeetion Vifi extending parallel to and out ot alineinent with the axis ol the .shalt 44. The top ol' the \alve head IL is tort-,ed into constant eontaet with this eeeem'rie pro jeetion by the spring ll and the projeetionft so arranged that when the shaft 44 and stem fl-l'l are turned as a unit the 'valves 37 and may be simultaneously moved from the position shown in Fig. l to the position shown in Fig. Q and haelt again. The outer end ot' the shaft ll extends be yond the tubular stem `i() and has an arm -lt tiXed thereto whieh arm lies adjaeent the arm 43 which is carried by the stem lo. The two arms i3 and itl are seeured together by means ot a serew 47 extending through a, slot 48 in the arm lli and threaded into the arm 43 so that tht stein Aitl and shaft il will move as a unit when the arm #iii is operated. y[he slot 48 is so arranged that the arm l'lli and shaft il may be adjusted about the axis o't' the stem itl by loosening the .serew Yli and thereby permitting the position oll the projet-tion 4-5 with respeet to the valve Il? to be changed and thereby permitting thel timing ot the operation ot the valve 52 with respect to the movement ot the valve li to lanirely regulated. 'lv'he inov'fnnnt oi' the arm Yl and the valve iii in one dii'eetion to the position ot the valve ,shown in l is limited by a .stop lll 'irojeeting l'i'om the end wall iti ol' the easing il and adapted to engage a projeetion Si() earried by the arm lil; and the movement, of the arm l and valve Iii in the, re4v versed direetion to or near the position .shown in, big. 2 is limited b v a .similar stop 5l likewise ear 'ied by the end wall lz.' ol' the -asing f).

'l`he oil is supplied to the li'haniber l5 through an inlet ,32 whieh extends eentrallvv through a nipple ."il whieli extends' from the lower part of the iazliug ll.
